GL: Optimize multi-view layered Clear* commands Until this patch multi-view layered framebuffers used to be cleared by attaching a single layer of each attachment to a framebuffer and calling the Clear* command for that internal framebuffer. According to the GL 4.1+ specifications, Clear* commands clear all of the layers of an attached 2D texture array. If all of the layers are active for a multi-view layered framebuffer, then we can directly call the corresponding Clear* command instead of iterating over each layer and clearing it.
